Attempted to get mine remapped today. The guy said he needed to leave the car for 40 minutes before he could start the up load. But for some reason the car had been left ages, but wouldn't take it because it believed it had been started!!

Some ECUs have issues with some tools where the ECU needs to be "woken up"

On some vehicles i leave them idling for some time and then start the process which is usually fine..

If not, you can read the PPD Siemens on the bench anyway..
